--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Is this reduced from some other code because this code seems undefined.

That is :
    uint16_t lfsr = 0xACE1u;

...

      goto *labels[lfsr & mask];


Will be 0x11 for the inner most loop always and labels has only three elements.
